incomplete window capturing (set image [image create photo -format "window" -data "$pWidget"])

[lem...@gmail.com]

Hi,

I need to make snapshot of widget in order to fgenerate some documentation in my tool. After some research the Img::window package seems to be (almost) perfect.

The problem is i mostly have incomplete image generation, even if the widget is visible.

I "topmost" the toplevel window, i raise it, i raise the specific widget, i update before createing the photo. The first time, it works, but after that it does not :(

Is there known bugs (i'm using the 1.4.3 version of Img package and tcl 8.5.18).

Thanks,
Jérôme Legrand

Wouldn't a standard system snapshot tool work out better? The linux flavors all have some sort of 'screenshot' tool, Windows has their snipping tool.

It is a possibility but it would much more complex that the the simple code to grab the widget image and it would not have the same possibility : i switch between widget in order to produce image for an automatically generated documentation. I m not sure i can do the same with an external tool.

Right. For automatically generated documentation, an external tool would be difficult. Unfortunately, I'm not using that part of the Img package, so can't help with that. You'll have to see if anyone else is familiar with it.

A little bit offtopic but I regularly use "rbc::winop snap" to create live images under windows.

For docu I use the following proc. Activate it with "snapwidget on" and then get the image with F12.

proc snapwidget {mode} {
switch -- $mode {
on {
bind all <Enter> {set ::ztk::snapwidget %W}
bind all <Key-F12> {::ztk::snapwidget do}
}
off {
bind all <Key-F12> {}
}
do {
if {![winfo exists $::ztk::snapwidget]} return
catch {image delete __snap}
catch {destroy .__snap}
image create photo __snap
::rbc::winop snap $::ztk::snapwidget __snap
toplevel .__snap
wm overrideredirect .__snap 1
wm geometry .__snap +100+1
bind .__snap <Key-Delete> {destroy .__snap}
::grid [::label .__snap.l -image __snap]
wm deiconify .__snap
}
}
}

Yes i've seen the blt package but of course it is not compatible with tcl 8.5 or 8.6 :(

That's why you could consider rbc: contains the essentials of blt and
*is* compatible with 8.5/8.6...
